CWS Organizational WLAN Goals Questions and Answers

Question 1

A university is designing a WLAN for a large lecture hall that will host over 300 students, each using a laptop for online activities. Which organizational goal is the MOST critical to address in this high-density environment?

Accepted Answer

Capacity

Answer

In a high-density environment like a lecture hall, the primary goal is capacity. Capacity planning ensures the network can handle the large number of simultaneous connections and the aggregate throughput demands of many users and their applications. While coverage (signal presence) is necessary, it is secondary to ensuring the network has enough capacity to serve all connected devices effectively.

Question 2

An organization plans to implement a Voice over Wi-Fi (VoWiFi) system for its employees who move throughout a large warehouse. Which two WLAN design goals are MOST important for ensuring reliable call quality and preventing dropped calls?

Accepted Answer

Seamless roaming and QoS

Answer

For real-time applications like VoWiFi, seamless roaming is crucial to hand off calls between access points without interruption as users move. Quality of Service (QoS) is essential to prioritize voice traffic over less time-sensitive data, ensuring low latency and jitter, which directly impacts call quality.

Question 3

Which of the following BEST defines the organizational goal of 'coverage' in a WLAN design?

Accepted Answer

Providing a minimum signal strength level throughout all required physical areas.

Answer

The primary goal of coverage is to ensure that a usable Wi-Fi signal is available in all designated areas of a facility. This is typically defined by a minimum signal strength threshold, such as -67 dBm, to guarantee that devices can connect and maintain a stable connection.

Question 4

A retail company wants to deploy guest Wi-Fi in its stores. A primary business requirement is to track customer movement patterns and dwell times to optimize store layout. This business need translates directly into which technical WLAN goal?

Accepted Answer

Design for location-based services

Answer

Tracking user movement and dwell times is the primary function of location-based services (LBS). The WLAN design must support this by having an appropriate density and placement of access points to enable accurate device location tracking.

Question 5

During the initial planning phase for a new WLAN, what is the primary purpose of defining the types of devices and applications that will use the network?

Accepted Answer

To establish the capacity and performance requirements.

Answer

Understanding the devices (e.g., laptops, VoIP phones, barcode scanners) and applications (e.g., web browsing, video streaming, database access) is fundamental to defining the capacity requirements. Different devices have different capabilities, and different applications have varying demands for throughput, latency, and jitter, which directly shapes the performance goals of the WLAN design.
